Abstract: 722,859. Traversers for handling vehicles. SANDERS, L. K., and SANDERS, V. A. Oct. 13, 1952, No. 25592/52. Classes 78 (4) and 104 (2). A vehicle parking apparatus for a multilevel storage structure has an elevator mounted for vertical movement in an upright guide frame, a transfer vehicle carrier horizontally reciprocable on the elevator and movable in the same plane as that on which the vehicle to be parked is standing and provided with jack means for lifting the vehicle and supporting it during the horizontal transfer movement of the carrier. The parking place comprises two spaced columns of rows of parking stalls and the motors are transferred to these stalls by a carrier 5 running on tracks T between the columns and having thereon an elevator E and a horizontally travelling carrier 54 with jacking device. The carrier 5 has front rollers 7 driven by an air motor 12 and shaft 11 operated by a pump 79 and motor 78 and controlled by an attendant at 81. The carrier is guided by uprights 15 braced at the front and rear and having side beams 18 with channels spaced to coincide with the floor levels. The elevator E, Fig. 4, is raised and lowered by a hydraulic ram 28 through pairs of duplex cables 20, 30. The cables 20 are anchored at one end to the elevator and pass over pulleys 22 at the tops of the uprights 15, round pulleys 23 and 24 on the ram head, round pulleys 25 on the piston head 26 to anchorage 29 on the ram head. The cables 30 pass round pulleys 31 and 32 on the ram head, round pulleys 25 on the piston head to anchorage 29. The piston head moves between guides 84. The ram 28 is supplied with fluid through pipes 83 and compressor 82 actuated by the motor 78. The elevator is held in position by spring-urged latches on the elevator co-operating with projection 34 on the uprights 15. The latches are releasable by a pedal. A slide 50 is connected to I bars 51 having rollers 53 journalled therein which run on guide tracks 49 on the elevator. A carrier 54 is mounted on the slide by corner jacks supported on the I bars. The jacks are operated by a motor 57 and pump 58 and pipe lines 60 controlled by mechanism 61. The pump 58 also operates an air motor 62 which operates a drum 63 carrying duplex cables 64, 65. Cable 65 passes around pulleys 66 and 66b to one end 68 of the slide 50 and cable 64 passes around pulleys 66 and 66a to the other end 69 of the slide. By operating the pump 58 and motor 62 the slide is translated. The carrier is simultaneously translated by cables 70, 74 connected at one end to the elevator at 73, 77, and after passing round pulleys 72, 76 on the slide are anchored at 71, 75 to the slide.

Abstract: A cleaning composition for textiles, wallpaper, leather and other skin surfaces comprises (a) 5-30% by weight of silica aerogel; (b) up to 40% of a stain solvent; and (c) up to 94% of benzene or a liquid chlorinated hydrocarbon.  Component (b) may be a liquid chlorinated hydrocarbon such as carbon tetrachloride, chloroform, tri- or per-chlorethylene, an alcohol such as isopropanol or butanol, dioxane, or benzene, and in the simplest embodiments (b) and (c) are the same substance.  It is, however, preferred that (b) and (c) should be different substances.  The compositions may also include up to 3% each of an inert material, such as powdered starch, and a "reodorant" liquid.  In such cases, the amounts of (a) and (c) respectively are reduced accordingly.  Many suitable gel-like formulations are described; these are preferably packed in a deformable metal or plastic container and so may be extruded and spread on the material to be cleaned.  After a short time, the solvents evaporate and the silica may then be brushed off.

A refrigerator comprises an outer casing made up of a plurality of separate members, the front edges of the side walls of the casing being bent inwardly and arranged to overlap the outwardly bent edges of the inner liner, and foamed plastic insulation between the shell and liner. As shown in Fig. 3, the outwardly bent edge 11 of the inner line 7 abuts a return bend portion of the inwardly bent front edge of a side wall 1, the abutting parts being embraced by a sealing strip 5 which serves to prevent emergence of foam during formation of the insulation. The foamed plastic serves to hold the abutting parts firmly together. As shown in Fig. 15 a transverse frame member 3 is secured in a similar manner to the upwardly bent top edge of liner 7 and is so shaped as to overhang the refrigerator door (not shown). A top cover 6 is provided and a further frame member 4 (Fig. 1, not shown) is secured to the bottom of the liner. Alternative forms of connection between the edges of the inner liner and side walls, with and without the use of sealing strips, are illustrated in Figs. 7 to 14 (not shown). The refrigerator door (Figs. 18 to 22, not shown) is formed of two or more wall portions which are held together by means of foamed plastic insulation and serve to support magnetic sealing strips.

Abstract: 974,555. Refrigerating. TRANE CO. June 27, 1963 [Aug. 15, 1962], No. 25708/63. Heading F4H. [Also in Division H2] In a refrigeration system com prising a motor-driven compressol the motor is cooled by liquid refrigerant supplied thereto from the condenser via an economizer and liquid refrigerant is only supplied from the economizer to the evaporator when the level of refrigerant in the motor casing reaches a predetermined value. As shown in Fig. 1, the system comprises first and second stage compressors 12, 14 driven by a motor 10, a condenser 22, an economizer 27 mounted on the motor casing and an evaporator 70. Liquid refrigerant from the condenser passes to the economizer through a line 26 and thence to the motor casing to cool the stator 38. Refrigerant vapour from the economizer and the motor casing passes through a line 62 to a line 16 linking the compressor stages while liquid refrigerant passes from the economizer to the evaporator 70 when the refrigerant level reaches that of an outlet line 64. Annular passages are formed in the stator to permit liquid refrigerant circulation and the rotor 56 is disposed in a separate sealed compartment filled with refrigerant vapour which is circulated by fan blades 58 formed on the rotor to cool the latter and the end windings 59 of the stator. In the embodiment of Fig. 4, the economizer 82 communicates with the bottom of the motor easing through a line 88 which communicates at its upper end with a conduit 92 leading to the evaporator so that liquid refrigerant only passes to the evaporator when the liquid level in line 88, and hence in the motor casing, reaches the inlet to conduit 92.

Abstract: <PICT:0903222/IV (b)/1> Textile material is caused to travel through a bath of liquid in which transverse currents are so set up in the liquid outwardly from the centre line of the material that transverse stretching of the material occurs while it travels longitudinally. The material while being subjected to the action of transverse currents may be simultaneously vibrated by directing jets of liquid thereat.  Preferably the jets directed at each part of the material have a component motion in the same direction as the current stretching the same part.  Apparatus suitable for treating textile material is described above comprises a container, an agitating roller mounted about a horizontal axis within the container and having two helical vanes on it, one running with lefthand pitch outwards from the centre in one direction and the other with right-hand pitch outwards from the centre in the other direction, and guide rollers by which the material is caused to approach the vanes sufficiently <PICT:0903222/IV (b)/2> <PICT:0903222/IV (b)/3> <PICT:0903222/IV (b)/4> closely to be subjected to the currents set up by them during at least part of its travel through the container. Preferably the material approaches the vanes on opposite sides of the roller.  As shown in the Figures, agitating rollers 3, 4 may be carried in bearings supported by brackets within tank 1.  Each roller may be hollow and closed at each end.  Rollers 3, 4 may be driven in an anti-clockwise and a clockwise direction respectively such that material 13 passes in counter current to the peripheral movement of the rollers as it passes therebetween.  Water circulation may take place from tank 1 via rotary filter 15, pipe 16, pump 17, pipe 21, pipe 22 (having steam injector 23), perforated pipes 29, 291 and roller perforations 25, the latter permitting the material to be scoured by the ejection of liquid under pressure. Each vane may be a flat strip which is not only wound helically around the roller but also is fixed so that a line drawn transversely across its surface is inclined outwards towards the end of the drum from a plane passing through the drum normal to its axis and the perforations 25 in the roller lie close to the leading side of each vane.
